After a costly battle with Ohio Secretary of State Frank LaRose and Cleveland-area state Sen.
Matt Dolan, Moreno won. Their relentless attacks may hurt him this November
He'll face three-term Democratic U.S. Sen. Sherrod Brown, a veteran of Ohio politics and one of the year's most vulnerable Democrats.
An increasingly Republican state is predicted to have a heated general election. Brown's seat is likely to be a priority
GOP target as Democrats hold a 51-49 Senate majority but are defending more seats than Republicans.
He is the only non-judicial statewide Democrat in Ohio, which has shifted right under Trump.
Senate Majority PAC, an independent group allied with Majority Leader Chuck Schumer,
paid $2.7 million to boost Moreno's primary effort in the hope that he would be weakest against Brown come November, drawing bipartisan criticism.
